Of course... the best and fastest way is to place the IPK-file on a USB stick. Then insert it into the set-top box. Then, in the GUI MENU, search for the installation of the IPK package from the USB key.
But... if the software manager is not available as @Frenske writes, then that is bad. It needs to be installed (you can find it among all available plugins) :-).
IPK can be installed even after connecting via a terminal. However, you need basic IT experience for that.
For terminal connection with the set-top box, you can use PuTTY application for PC. Enter the IP address of your set-top box (this can also be found via the GUI MENU, in the network information). Choose a terminal connection - via the "other: Telnet" protocol. When you connect to the set-to box, the login name is root and the password is empty (just press enter). There you can use the package manager:
opkg install /tmp/*.ipk
Or with the exact filename, which is a much safer ipk installation step from a security point of view:
opkg install /tmp/YOUR-FILE-NAME.ipk
Then reboot the set-top box if necessary. Or use the reboot command in a terminal. Or use the Enigma2 quick-reboot: init 4; sleep 5; init 3
